TORNATINID^E, RINGICULID^. 233 



Tornatina parviplica BALL, Bull. Mus. Comp. Zool, xxv, no. 9, 

 p. 115, fig. 8 (Oct., 1894). 



RETUSA \_Coleophysis] EFFUSA Monts. (II Naturaliste Siciliano, 

 ix, p. 188, 1890) is an insufficiently described form from Villa- 

 franca. 



RETUSA OVATA Jeffreys (Vol. xv, p. 232). See Norman, Ann. 

 Mag. N. H. (6), vi, p. 64, for a discussion of the synonymy and 

 range. 



BULLA CRETICA Forbes. B. testa globosa, alba, Irevigata, spira 

 manifesta, umbilicata, margine rotundata ; apertura superne con- 

 tracta, inferne dilatata ; columella perforata. Long -1 unc. Crete, 

 in 119 fms. (Capt. Graves, 1843). (Forbes, in Rep. JEgean Invert., 

 Rep. Brit. Asso. Adv. Sci. for 1843, p. 188, 1844. 



An unrecognized form, perhaps belonging to Retusa or Cylichna. 



Acrostemma Cossmann, 1895. 



Ess. Pal. Comp., p. 101. Type Bulla coronata Lam., Eocene. 

 The recent B. striatula Forbes (Vol. xv, p. 212) is placed in this 

 group, which is ranged as a subgenus under Roxania by Cossmann. 



Family RINGICULIDJK. 

 Genus RINGICULA (Vol. xv, p. 394). 



Cossmanu substitutes Ringiculella Sacco, 1892, type R. auriculata 

 for Ringiculina Monts., 1884, but the latter should, I believe, be re- 

 tained, if the group is worth a name. 



Genus PUGNUS Hedley, 1896. 



Pugnus HEDLEY, Records of the Australian Museum, ii, no. 7, p. 

 106. 



By its thrice folded columella, anterior canal, thickened outer lip, 

 and sculpture of spiral grooves crossed by transverse stride, this very 

 distinct genus takes a place in the family Ringiculidse. From the 

 only other surviving genus, Ringieula, Pugnus is separated by its 

 involute shell and buried spire. In the shortness of the spire the 

 Cretaceous fossil Avellana occupies a position intermediate between 

 these two. Its contour is, however, more globose, and those subor- 

 dinate groups which agree with Pugnus in possessing a smooth lip, 

 appear to differ by having one columella plication only. (Hedley}.
